All of our Minerals & Crystals are 100% Genuine Specimens & come with a Certificate of Authenticity
These are special Tumblestones that have been produced from some of the most beautiful, and sometimes hard to obtain, minerals from around the world. These specimens are sold as individual stones.
Tumblestones or “tumbled stones” as they are also referred to are made by “tumbling” rough crystals, minerals or rocks in grit for a number of days in a tumbler machine. Different grades of grit are used in the process until the rough edges are smoothed, then polish is added to bring a soft shiny surface to the specimen. Because of this process each stone will be unique in shape and colour.
Agate is a variety of silica, characterised by its fineness of grain and brightness of colour. Agate is one of the most common materials used in the art of hardstone carving and are used to make ornaments such as pins, brooches or other types of jewellery, Most agates occur as nodules in volcanic rocks or ancient lavas.
